Terrestrial jitter sometimes increases when data is sent across the P ublic S witched T elecom
N etwork (PSTN).
Wide corresponds to about 2 Hz and Narrow is approximately 0.5 Hz. Normally, the Wide
selection is adequate, but when higher amounts of terrestrial jitter are present in the incoming
ASI data stream the
Narrow setting will help reduce jitter.
